Unmodified, epoxy resins cause certain problems for both the adhesive formulator and end-user. They are often rigid and brittle; hence, impact resistance and peel strength are poor. For decades, Chemist have been vigorously working to minimize these major shortcomings. Based on a popular course sponsored by the Society of Plastics Engineers and written by an authority in the field, this comprehensive text presents a variety of methods to accomplish what up to now has been a formidable task. Beginning with epoxy chemistry, moving on to fillers, filler treatments, and surfactants, and ending with current and future development in formulating Epoxy Adhesives, this rigorous text addressed the problem of improving flexibility, durability and strength by adding chemical groups to the epoxy structure either via the base resin or the curing agent or by adding separate flexibilizing resins to the formulation to create an epoxy-hybrid adhesive.

Epoxy resins have been commercially available for about 45 years and now have many major industrial applications, especially where technical advantages warrant their somewhat higher costs. The chemistry of these resins is fascinating and has attracted study by many very able scientists. The technological applications of the epoxy resins are very demanding and there are many new developments each year. The aims of the present book are to present in a compact form both theoretical and practical information that will assist in the study, research and innovations in the field of epoxy resin science and technology. The literature on epoxy resins is so vast that it is not possible to be encyclopaedic and that is not the function of the present text. It is the editor's hope that the selection of topics discussed will provide an up-to-date survey. There is some overlap in the chapters but this is minimal and so each chapter is essentially self contained. As with all chemicals there are toxicological and other hazards. These are not dealt with in this text since a little knowledge can be dangerous, but material supplied can provide information regarding any safety precautions that may be necessary. However, often these precautions are not onerous and epoxy resins, or more specifically the hardeners, can be handled readily. It is hoped that this text will provide an up-to-date outline of the science and technology of epoxy resins and stimulate further research into unsolved problems and assist further technological developments.
The Handbook of Adhesives and Sealants, 2nd Edition is primarily written to assist all those who have a permanent or temporary interest in adhesives and sealants. For those new to the field, the Handbook will provide a fundamental knowledge base of materials and processes as well as reasons why they work and (more importantly) why they don’t work. To the more experienced reader, the breadth and thoroughness of the Handbook will provide a way to reduce time spent on trial and error development or on searching for the optimal recommended process. For the academic, the Handbook will connect the important theories regarding surface science, polymeric materials, and mechanics with practical products and applications of commercial significance. This edition includes major new sections on radiation curable adhesive, biological and naturally occurring adhesives, inorganic adhesives, role of bulk properties of the adhesive, non-destructive testing, and industrial application methods. A completely new chapter is devoted to adhesives used in various industries such as automobile, electrical / electronic, construction, packaging, aerospace, household do-it-yourself, and medical.
This book presents a review of research on the use of epoxy resins as consolidants for sculpture and buildings. It deals with both the methods and materials used by conservators, focusing on a detailed chemistry of the materials as well as the practical methods of application. Epoxy resins have been widely used as structural adhesives to repair cracks in commercial and historic buildings, but the application of this technology to the stabilization of fragile stone has generally failed. However, the proper formulation of epoxy systems with solvents has solved problems of viscosity, penetration, crust formation, and discoloration, leading to two different schools of treatment detailed in the publication. Conservators in Europe have concentrated on the treatment of statuary and isolated sections of structures, with alcohol solutions of the resins maintained in contact with the surface for a period of time in order to get deep penetration. In the United States, treatment has focused on stabilizing entire structures or major portions of buildings by spraying them with acetone solutions of epoxy resins. The various techniques of application are discussed and evaluated. The book seeks to provide an expanded inventory of these different techniques allowing the conservator to make informed judgments.

Epoxy is a term used to denote both the basic components and the cured end products of epoxy resins, as well as a colloquial name for the epoxide functional group. Epoxy resin are a class of thermoset materials used extensively in structural and specialty composite applications because they offer a unique combination of properties that are unattainable with other thermoset resins. Epoxies are monomers or prepolymers that further reacts with curing agents to yield high performance thermosetting plastics. They have gained wide acceptance in protecting coatings, electrical and structural applications because of their exceptional combination of properties such as toughness, adhesion, chemical resistance and superior electrical properties. Epoxy resins are characterized by the presence of a three membered cycle ether group commonly referred to as an epoxy group 1,2-epoxide, or oxirane. The most widely used epoxy resins are diglycidyl ethers of bisphenol-A derived from bisphenol-A and epichlorohydrin. The market of epoxy resins are growing day by day. Today the total business of this product is more than 100 crores. Epoxy resins are used for about 75% of wind blades currently produced worldwide, while polyester resins account for the remaining 25%. A standard 1.5-MW (megawatt) wind turbine has approximately 10 tonnes of epoxy in its blades. Traditionally, the markets for epoxy resins have been driven by demand generated primarily in areas of adhesives, building and civil construction, electrical insulation, printed circuit boards, and protective coatings for consumer durables, amongst others. The major contents of the book are synthesis and characteristics of epoxy resin, manufacture of epoxy resins, epoxide curing reactions, the dynamic mechanical properties of epoxy resins, physical and chemical properties of epoxy resins, epoxy resin adhesives, epoxy resin coatings, epoxy coating give into water, electrical and electronic applications, analysis of epoxides and epoxy resins and the toxicology of epoxy resins. It will be a standard reference book for professionals and entrepreneurs. Those who are interested in this field can find the complete information from manufacture to final uses of epoxy resin. This presentation will be very helpful to new entrepreneurs, technocrats, research scholars, libraries and existing units.
This eBook teaches adhesive and sealant formulation in two steps. Each section first describes the application and chemical basis of the type of adhesive or sealant concerned. This is followed by formulation advice and - if possible - an analysis of existing recipes. This analysis includes a calculation of the important characteristic values of the formulations. All calculations based on recipes and formulations are worked through step by step and should therefore be intelligible to beginners, too. ur choice as well as to download and transfer it up to five additional devices in your possession.You can save the downloaded content on each of the individual devices once to view it unlimited times.
Both solid knowledge of the basics as well as expert knowledge is needed to create rigid, long-lasting and material-specific adhesions in the industrial or trade sectors. Information that is extremely difficult and time-consuming to find in the current literature. Written by specialists in various disciplines from both academia and industry, this handbook is the very first to provide such comprehensive knowledge in a compact and well-structured form. Alongside such traditional fields as the properties, chemistry and characteristic behavior of adhesives and adhesive joints, it also treats in detail current practical questions and the manifold applications for adhesives.
